GEORGE H. FERRIS, OF BROOKLYN, NEW YORK.

OIL-LAMP STOVE.

SPECIFICATION forming part of Letters Patent No. 268,655, dated December 5, 1882.

' Application filed November 16, 1877.

To all whom -it may concern:

Beit known that I, GEORGE H. FERRIs, of Brooklyn, in the county of Kings and State of New York, have invented certain new and usev ful Improvements in Oil-Lamp Stoves; and I do hereby declare the following to be a full, clear, and exact description ot' the same, reference being had to the accompanying drawings, forming a part of this specification, and in which-' Figure l represents a longitudinal vertical 'section of an .oil-lamp stove constructed in ac 'I `will .irst describe, and then point out particularly in the claims. A

In the drawings, A. represents the base of the stove, having an oil-chamber, B, and supporting-legs C.

D is the drum or body of the stove, having lateral arms d, bywhich it is supported in bearings e in upwardly-projecting lugs E-preferably three in numberoli the base, as shown in Figs. l and 2. The drum is divided into three compartmentsor fines, D D2 D3, by means of partitions ff, and it has a bottom plate, D, through openings in which the lamp-Wicks are adapted to pass. l

Formed upon or bolted or otherwise firmly secured to the upper end of the drum is the top ofthe stove, G. This top has three openings, G G2 G3, in its bottom, leading respect- 'ively from the iiues D Dz D3, and it also has lateral extensions, preferably four in number, H' H2 H3 H4. The extensions each havealateral discharge opening, h, for the heat, and some or all of them are provided with a suitable valve, which, when turned in position, is adapted to close the heat-discharge openings, and when turned in another position is adapted to prevent the heat from entering said extenl sions from the heat-dues of the drum. In Fig. 3 two `of the extensions, H H3, are represented as being larger than the other two extensions, H2 H4. The valves in the smaller extensions 5 5 are indicated by the letters I I They may he turned so as to wholly or partially excludethe hot air from the extensions or to permit of more or less of it escaping therefrom. In Figlet differentarrangements of valves are represented 6o in the various extensions. The construction ot' the top is such that a large vessel may be heated over the middle portion of it, and at the same time various smaller vessels may be subjected to greater or less heat in the several 6 5 extensions. The heat arising through the drum strikes the bottom of the large central vessel and is deflected into the extensions, thereby being doubly utilized. When a central vessel is not in position a plate or web, J, is placed 7o over the center of the top, as shown in Figs. 3 and 4, and said plate then serves to deflect the heat into the extensions, the same as the large vessel does when it is used. The top and its extensions being permanently affixed to the drum 7 5 or body of the stove, the latter can be tilted on its articulated bearings to permit of access to the lamp, or for any other purpose,without the necessity of lifting oif a top, as in the case of the ordinary oil-stoves. 8o

K represents a metal plate forming the top of the oil-chamber B. This plate has a central tube, 7c, and angular corner-pieces 7c', as shown in Fig. 2. Resting upon the tube It and held in place by the corner-pieces la is another plate, 8 5 L, to which the wick-tubes l l lare attached, as shown iu Figs. l and 2. rl`he wick-tubes extend up into the converging openingsin the bottom plate, D4, of the drum 5 but their lower ends terminate at or slightly below the plate 9o L, thus leaving an open space between them and the top plate of the oil-reservoir. Direct metallic communication between the wicktubes and the oil-reservoir is thus prevented, and the danger of generation of gases and explosion in the latter is obviated.

A perforated plate, N, may be ttedover the wick-tubes, if desired, as shown in Figs. l and 2.

. Prior to my invention all oil-stoves which roo have been adapted to the heating of several separate vessels at the same time have been provided with a removable top, which was capable of being placed upon and taken off ot' the drum or body of the stove, and which was a separate and independent structure in itself.

When the top was lifted the body ofthe stove was not disturbed, and -When the body 0f the stove was tipped in taking it oiits base with the top upon it the latter was liable to fall oi and become broken. The ordinary method of attaching the body of the stove'to the base consisted in forming vertical standards or posts on the base, and in providingin the bottom plate of the body a series of holes or perforations for the reception ot the said standards or posts of the base. When it was desired, for any purpose, to get. at the heating-lamps, it was necessary to lift the whole body ot' the stove until it was clear of the base, and then set it to one side while inspecting or arranging the lamps. So, too, in prior oil-stoves no means of controlling the admission of heat into the several lateral extensions of the top or of cutiing the heat off therefrom was employed, and the consequence was that when the opening in any one of the lateral extensions was left uncovered by the removal of a vessel or covering-plate therefrom the heat all tended toward that opening as the easiest avenue of escape, and the otherA extensions were not properly or sufficiently heated.

My invention, it will be observethobviates all the above-named objections to the old form of oil-stoves. ln the iii-st place, the top and body ofthe stove are so connected together as to form practically a single structure, or, in other Words. the body merges into the-top and the lateral-extensions of the latter form simply continuaiions of the ilue or dues in the body. When the top is moved the body is also moved,and the formercannotfallottwhen the body is tipped. So, therefore, when it is desired to inspect the lamps, it is not necessary to take oli' first the top and then the body, but both are removed out of the Way as a unity. In the second place, the body of the stove is articulated to the base, so that when it is desired to have access to the lamps it is only necessary to tip the body ofthe stove in its articulated bearings to effect the object, Without the labor of lifting the body entirely from the base, and then after fixing the lamps placing the body back upon the base with the openings in its lower plate properly registered with standards or posts on the base, as heretofore, and this turning or tilting of the body does not permit of the top falling o, as the latter is formed integral with it, as aforesaid. In the third place, by the valves which I employ in the upper part'of the stove I am enabled to admit the heat into any or all of the lateral extensions in any desired quantity, or to entirely exclude it therefrom at pleasure, and by such an arrangement all the extensions of the top maybe utilized for cooking dii'erent articles at the same time under different degrees of heat, and when a vessel is removed from one of the extensions the valve in that extension can be closed, so as to prevent the flowing out ofthe heat through that extension and the diminishing of the heat in the other extensions. The lateral opening of each of the extensions laffords the necessary exit for the heated air when the valves are partially or wholly opened. The valves are so arranged that while they are capable of controlling the quantity of heat admitted into the extensions, they are also adapted by co-operation with the discharge-openings to regulate the amount of heated air discharged from the extensions. tion in my stove, it will be seen, make it a greatly superior structure to the oil-stoves that have preceded it.

There are several features of my herein-described oil-stove which I have not claimed herein` as they form the subject-matter of a separate application-a division of thepresent case, designated as Division B.

I claim as my inventionl. An oil-stove having a vheat-conducting drum, a rigidly-attached top having lateral extensions or vessel-supports, and valves for controlling the admission of heat into the extensions, substantially as described.

2. An oil-stove having a' heat-conducting drum, a rigidly-attached top having lateral extensions or vessel-supports7 a central heatdetlecting plate or web, and valves for controlling the. admission of heat into the extensions, substantially as described.

3. The combination, with the oil-reservoir, of the plate K, having the central tubular support and the angular corner-pieces, and the plate L, carrying the wich-tube, the. whole arranged and operating` substantially as described.

4. An oil stove provided with a top having lateral extensions, each adapted to hold a separate vessel. and having valves for controlling the admission of heat into the several extensions, substantially as described.

5. In an oil-stove, the combination of the following elements, viz: a body or drum having one or more heat-conducting fines, a top having openings corresponding to the number of flues, and having lateral extensions with open tops for holding and receiving separate vessels, some of said extensions having the heat-lines of the drum opening directly into them, and others of said extensions being removed from said lines and receiving only such heat asis laterally deiiected into them after emerging from the tlues of the drum, and having rests for supporting a central vessel or deiiectingplate, as described, a base-plate for the body or drum, means for rigidly connecting the extension-iop to the base-plate, so as to hold the structure solidly and permanently togethcr, and a base containing a lamp or lamps, upon which the stove-body rests, as set forth.

6. ln an oil or gas stove, a top having a lateral extension provided with a valve capable of closing either the entrance to or the exit from said extensions.
